In https://reviews.llvm.org/D71059 LLVM 11, the time trace profiler was extended to support multiple threads. `timeTraceProfilerInitialize` creates a thread local profiler instance. When a thread finishes `timeTraceProfilerFinishThread` moves a thread local instance into a global collection of instances. Finally when all codegen work is complete `timeTraceProfilerWrite` writes data from the current thread local instance and the instances in global collection of instances. Previously, the profiler was intialized on a single thread only. Since this thread performs no code generation on its own, the resulting profile was empty. Update LLVM codegen to initialize & finish time trace profiler on each code generation thread. |
